Solutions for IDY production - Oerlikon Barmag - Oerlikon Textile

There are numerous possibilities for sustainably lowering the
consumption of valuable resources. Firstly, there are energyoptimized
components, for example Oerlikon Barmag’s SP8x
spinning beam, which consumes more than 40% less energy
than other more common designs.
Reducing the consumption of controlled-processed air is
an important objective of a radial quenching system. Such
a system consumes 60-80% less air than cross-flow
quenching – it is available for the production of HMLS yarns
with a high number of filaments.
The influence of godets on the energy efficiency of a spinning
system is also remarkable. The main effect of the HF
godet technology is that the energy is only fed to the shell of
the godet itself, the only part of the godet that actually needs
to be heated. With the standard 50-Hz heating technology,
this skin effect is negligible. For this reason, the 50-Hz heater
needs at least 20% more energy which results from the
power loss caused by heat distribution in the heater tube,
the shaft and the front of the shell.
signed spin packs, one quenching unit and one draw panel
on two winders is therefore considerably more efficient than
two 8- or 12-end spinning positions.
A decisive associated factor influencing the overall energy
consumption is the air-conditioning system. Drives, heating
systems, components that come into contact with the
melt and the filaments radiate heat. If this heat radiation is
reduced by means of excellent insulation, the air-conditioning
system can be small, hence itself using less energy. Furthermore,
water-cooled godets and electrics generate a further
reduction of the heat load within the take-up area.
Oerlikon Barmag – with its focus on innovation and
technological leadership – provides a variety of machines,
components and solutions that stand out through their
excellent resource efficiency and thus easily fulfill the
requirements defined by the e-save label.
Another advantage of the HF technology is the fast heat-up
caused by the direct energy transfer, meaning that Barmag
godets react extremely fast to changes.
Multi-end filament spinning saves energy
However, the utilization of efficient components is only one
step on the path to creating smart production processes.
Restricting the examination to the spinning system alone
does not take important factors into account. Within this
context, the multi-end filament capability should definitely
be considered as an energy-saving factor. Spinning 16- or
